If your nose won’t stop running and your eyes won’t stop itching, your zip code might be partly to blame. New research reveals that some American cities have become absolute minefields for allergy sufferers – and climate change is making the situation progressively worse.
The Allergy Epidemic
According to the Asthma and Allergy Foundation of America’s 2025 report, pollen seasons are starting earlier and lasting longer across the country. “We’re seeing a dramatic increase in both the duration and intensity of allergy seasons,” explains Dr. William Anderson, an allergy specialist at the University of Colorado. “What used to be a seasonal nuisance is becoming a year-round health concern for many Americans.”
How Pollen Wreaks Havoc
Pollen – the microscopic powder released by plants – triggers an immune overreaction in allergy sufferers. When inhaled, the body mistakenly identifies these harmless particles as dangerous invaders, unleashing a wave of histamines that cause classic allergy symptoms:
- Sneezing fits
- Runny or stuffy nose
- Itchy, watery eyes
- Scratchy throat
The worst offenders come in three varieties:
- Tree pollen (spring)
- Grass pollen (summer)
- Weed pollen (fall)
2025’s Allergy Capitals
This year’s ranking analyzed three key factors: daily pollen counts, over-the-counter medication sales, and availability of allergy specialists. The dubious honor of worst cities goes to:
- Wichita, KS (3-year reigning champion)
- New Orleans, LA
- Oklahoma City, OK
- Tulsa, OK
- Memphis, TN
Southern cities dominated the list, thanks to their warm, humid climates that create ideal growing conditions for pollen-producing plants. But the biggest surprise came from California, where several cities saw dramatic jumps in rankings due to surging grass and weed pollen levels.
Climate Change Connection
The report paints a worrying picture of our pollen-filled future:
- Pollen seasons now start 20 days earlier than in the 1990s
- Seasons last 10 days longer on average
- By 2100, spring pollen could arrive 40 days earlier
- Summer/Fall pollen may linger 15 days longer
“Warmer temperatures mean plants grow faster and produce more pollen,” explains Dr. Anderson. “Add increased CO2 levels that supercharge plant growth, and you have a perfect storm for allergy sufferers.”
Should You Relocate
While moving might seem tempting, experts caution against it. “You might escape one type of pollen only to develop allergies to new varieties,” warns Dr. Anderson. Instead, they recommend:
- Get tested to identify specific allergens
- Start medications before peak seasons
- Consider long-term solutions like immunotherapy
- Use HEPA filters and monitor pollen forecasts
Fighting Back Against Allergies
Effective strategies include:
Medications: Antihistamines, nasal sprays, eye drops
Home Care: Frequent cleaning, closed windows on high-pollen days
Prevention: Shower after outdoor activities, wear sunglasses/masks
“The key is being proactive rather than reactive,” advises Dr. Soliman. “With proper management, most people can find relief even in high-pollen areas.”
As pollen seasons continue to intensify, understanding your local risks and preparing accordingly may mean the difference between suffering through allergy season and breathing easy all year round.
